From appendixes A2/6 and A3/6: Military industry also specialized in UAV.

-This company manufactures defense products. They make very small engines for UAVs that are used for espionage and special military-type missions.

-Although they look like model airplanes, actually they are more complex both for their capacity and the load they carry.

"Israeli UAV"

-Usually they carry scanners and cameras of various types. They also use electric motors that make them silent.

-The B-013 UAV Propulsion Motor is suitable for Micro UAVs and Mini UAVs. They are of little power, weight and size. These brushless motors are very reliable and have a long life.

-They are sealed for protection against changing environments and weather conditions.

-These motors need a 6 or 12 volt power supply and batteries are a very important issue to make flights durable.

"Bental B-013 electric motor"

-Another motor is the B-020, which has 1.07 Nm of torque at 9200 rpm takeoff. It needs 30Vdc.

"Bental-020 electric motor"

-The larger one is the B-047, which operates at a voltage between 80-130 Vdc. On takeoff it runs at 6000 rpm, and  at full battery voltage (130) it reaches 7000 rpm. It supports 170 Vdc peak voltage.

"Bental B-047, version -017"

-Presumably Bental has a wider range, if not now, it will in the future. Other brands in all parts of the world are offering this type engines for this kind of missions.
